MC IS A TOP, a pretty top, ML is a muscular friends with everyone "clueless" bottom. He seems clueless but I don't think he is, he seems very aware of the peope around him. They got cursed by a rock and have red strings of fate attached to them, they must complete quests or suffer penalties. MC has a crush on ML but he doesn't think its reciprocated or that the ml has even the faintest clue
